Abstract
Troubles related to damage of fiber ropes for wiring have sometimes occurred in case of wiring works close to energized transmission lines. Therefore, in order to establish a guideline on the treatment of fiber ropes for wiring works near transmission lines, authors implemented a damage test on the condition of high electric field, then examined the damage characteristics and mechanism. In this paper, mechanism of the dry-band arcing occurring as a result of concentration of voltage across the dry-bands, which are generated by the joule heat caused by the current induced to the wet fiber rope, is shown. In addition, the occurrence condition of the dry-band arcing acquired by the applied voltage test is described.
